Debugging options

Command: /maint/debug

[Miscellaneous Debug		Menu]
tbuf	- Show	MP trace buffer
snap	- Show	MP snap (or post-mortem) trace buffer
clrcfg	- Clear all flash configs

The Miscellaneous Debug Menu displays trace buffer information about events that can be helpful in understanding switch operation. You can view the following information using the Debug Menu:

•Events traced by the management processor (MP)

•Events traced to a buffer area when a reset occurs

If the switch resets for any reason, the management processor (MP) trace buffer is saved into the snap trace buffer area. The output from these commands can be interpreted by HP technical support.

The following table describes the Miscellaneous Debug Menu options:

Table 188 Miscellaneous Debug Menu options

Command	Usage

tbuf	Displays the management processor trace buffer. Header information similar to the following is shown:
	MP trace buffer at 13:28:15 Fri May 25, 2002; mask: 0x2ffdf748
	The buffer information is displayed after the header.

snap	Displays the management processor snap (or post-mortem) trace buffer. This buffer contains information
	traced at the time that a reset occurred.

clrcfg	Deletes all flash configuration blocks. The next time the switch is rebooted, it returns to the factory default
	settings.

ARP cache options

Command: /maint/arp

[Address Resolution Protocol Menu]

find	- Show a single ARP entry by IP address
port	- Show ARP entries on a single port
vlan	- Show ARP entries on a single VLAN
addr	- Show ARP entries for switch's interfaces
dump	- Show all ARP entries
clear	- Clear ARP cache

The following table describes the Address Resolution Protocol Menu options:

Table 189 Address Resolution Protocol Menu options

Command	Usage

find <IP address>	Shows a single ARP entry by IP address. For example,
	192.4.17.35

port <port number>	Shows ARP entries on a single port.

vlan <1-4095>	Shows ARP entries on a single VLAN.

addr	Shows the list of IP addresses that the switch will respond to
	for ARP requests.

dump	Shows all ARP entries.

clear	Clears the entire ARP list from switch memory.

NOTE: To display all ARP entries currently held in the switch, or a portion according to one of the options listed on the menu above (find, port, vlan, dump), see the “ARP information” section of the “Information Menu” chapter.
